Barmac® B Series™ impact crushers - Outotec

Barmac® VSI crushers can be equipped with metallic anvils on request. In anvil solution the rock-on-rock cavity ring is replaced with an anvil ring. The anvil solution improves Barmac® crushers' reduction ratio and enables finer end products, but wear costs are slightly increased since the anvils must be replaced from time to time.

Types Of Vsi Crushers

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other. get more.

Mathematical modeling of a vertical shaft impact crusher ...

1. Introduction. Impact crushers have become particularly useful in manufactured aggregates production because of the nature of the breakage mechanisms, which allow direct fragmentation of the particles without leaving residual stress in them (Wills and Finch, 2016).As such, material produced in a particular size range, which may be controlled by the combination of crushing …

What Is A Vertical Shaft Impactor (VSI) Primer? | Stedman ...

VSI Benefits. When it comes to producing materials such as aggregate for road making, VSI crushers use a high-speed rotor and anvils for impact crushing rather than compression force for the energy needed for size reduction. In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or ...
